1.在要添加的项目中选中 依赖项->右键->管理NuGet程序包(N)
2.在NuGet包管理器中输入Autofac,安装选中文件
3.在项目中找到Program.cs文件,添加如下代码
public static IHostBuilder CreateHostBuilder(string[] args) => Host.CreateDefaultBuilder(args) .ConfigureWebHostDefaults(webBuilder => { webBuilder.UseStartup<Startup>(); }) // 添加依赖注入 .UseServiceProviderFactory(new AutofacServiceProviderFactory());
4.在项目中找到Startup.cs文件,添加如下代码
/// <summary> /// 依赖注入配置容器 /// </summary> /// <param name="builder"></param> public void ConfigureContainer(ContainerBuilder builder) { ////单个服务注入 //builder.RegisterType<OrderService>().As<IOrderService>(); // 获取 Service.dll 程序集服务,并注册 var assemblysService = Assembly.LoadFrom(Path.Combine(AppContext.BaseDirectory, "NetCoreWebApi.Service.dll")); // 获取 IService.dll 程序集服务,并注册 var assemblysIService = Assembly.LoadFrom(Path.Combine(AppContext.BaseDirectory, "NetCoreWebApi.IService.dll")); builder.RegisterAssemblyTypes(assemblysService) .AsImplementedInterfaces() .InstancePerDependency().PropertiesAutowired(PropertyWiringOptions.AllowCircularDependencies); builder.RegisterAssemblyTypes(assemblysIService) .AsImplementedInterfaces() .InstancePerDependency().PropertiesAutowired(PropertyWiringOptions.AllowCircularDependencies); }
5.添加好依赖注入,就可以直接在项目中使用
private readonly ISysRoleServices _sysRoleServices; public SysRoleController(ISysRoleServices sysRoleServices) { _sysRoleServices = sysRoleServices; }
